SanDisk is drawing aggressive long-term institutional buying that supports further upside. It posted its largest dollar buy volume ever at $1,646.55, a sign of institutions building a long-term position, and weekly high-dollar volume of $140B off the recent low supports a six-month upside continuation pattern. Selling from all-time highs looks inefficient, the monthly trend is bullish, and over $140M went into August 28 $900 calls. x.com  x.com  x.com 

Large option buyers are signaling something big ahead for SanDisk and the memory theme. Over the past week or so, whales have been loading up 2028 calls at strikes of $3,000 and above, and did so again today, after someone bought over $3.2 million of September 2027 $3,350 calls. x.com 

Sandisk is a tulip bubble on steroids, and such extremes end in losses of 97% or more. Its monthly RSI reached 99.5, and at the roughly $2,350 peak the price stood about 90% above its monthly 50-period moving average. The unwind is in line with the uninverting of the 10-year/3-month yield curve, and @StockSavvyShay notes Sandisk is in its biggest drawdown of the past year. x.com 

A large investor's bet signals serious conviction in SanDisk reaching $2,460 by December. The investor spent more than $2M on December $2,460 calls, about 55% out of the money, which is not a casual wager. Reaching $2,460 still requires a bull market, but it is not impossible. x.com 

Sandisk is drawing a massive put seller, a bullish signal for the stock. x.com 

SanDisk has run up about 3,000% since its 2025 IPO, turning a $10,000 investment into nearly $300,000 in a year. x.com 

SanDisk faces two near-term catalysts: Nasdaq-100 inclusion on April 20, which makes every tracking ETF and fund a forced buyer, and April 30 earnings showing a fundamental change. Consensus expects EPS of $13.90 versus a $0.30 loss a year ago and revenue of $4.61B versus $1.70B. The stock rose on Friday while the S&P 500 and Nasdaq fell. Analysts keep raising targets, all at Buy: Cantor Fitzgerald to $1,000, Bank of America to $900 and Citigroup to $875. x.com 

Institutions are buying the dip in Sandisk and Micron, which makes the pullback a chance to buy alongside them rather than a reason to be scared off. x.com 

Sandisk now has multi-year visibility from long-term customer contracts, yet trades at an estimated forward P/E of about 9 after falling roughly 45% from its highs. Scarred by 2023's price collapse, Sandisk, Micron, SK Hynix and Samsung are signing multi-year deals with large customer prepayments so buyers can't back out, with much supply sold into 2028 and some into 2029-2030. The market still discounts memory on past cycles, though it now has the most solid revenue base for 3-5 years. x.com 

SanDisk's FY28-FY30 targets are insanely positive, implying as much as $300-350 per share of annual free cash flow at the end of the period. SanDisk targets mid-to-high-teens revenue growth, about 80% non-GAAP gross margin and about 50% adjusted FCF margin, and plans to return 100% of excess cash to shareholders, effectively a $130 billion buyback over four years. x.com  x.com
